卷积相关公式的matlab代码
取半径=3
用matlab代码实现上式公式:
length=3;
for Ki = 1:length
for Kj = 1:length
for Kk = 1:length
Ksigma(Ki,Kj,Kk)=exp(-(Ki-2)^2/8-(Kj-2)^2/8-(Kk-2)^2/8); 此公式为:K(u), ρ=3
end
end
end
KONE = convn(ones(size(Img3D_mc,1),size(Img3D_mc,2),size(Img3D_mc,3)),Ksigma,'same'); 此公式为:∫k(x-y)dx
D_I(:,:,:,nn)= KONE.*Img(:,:,:,nn).^2-2*C(nn,kk)*Img(:,:,:,nn).*convn(B(:,:,:,nn),Ksigma,'same')+C(nn,kk)^2*convn(B(:,:,:,nn).^2,Ksigma,'same');
